  • Dayton Classic Revival - a smallish TMWW

    When PE put the DC50F mid dome on sale this month, I decided it was finally time to try a few ideas with them I'd always had in the back of my mind.

    First idea: a small, simple TMWW using the Dayton ND20FA6, DC50F, and two of the DC160 (run in parallel). The cabinet was easy, it's just the Amiga cabinet (geez, am I getting a lot of mileage out of that thing!). This is close to ideal, since the cabinet is ~ 30 Liters, which is within 10% of "ideal" for running two of the DC160. It gets an F3 of 34 Hz; not bad, eh?

    Whenever the DC160 is brought up, one of two things is said:
    1. harmonic distortion measures poorly
    2. it has a weak midrange, and could be a good woofer for a 3-way

    So why do we see so few 3-ways using it in the bass? Not sure, since the price is very attractive, and they do get a remarkably low F3 in a relatively small cabinet.

    Still, I'm not sure what the reaction will be to this design, since the Dayton Classic series has so many naysayers--TriTrix aside. I was very hesitant about even mentioning the project, just sort of showing up with it at Iowa. But that event looks pretty jam-packed, and I don't want to take more limelight than what's already been allotted to me. So instead, I'll just toss this out in the water and see if it gets any nibbles. If it doesn't, that's OK with me; doesn't change my opinion. On the whole I think the Dayton Classic series are pretty fun drivers to listen to, and no graphs can take that away from me. ;)

    I don't want to post the crossover yet, but I did a quick add-up of the parts cost and it's less than $210.

    I put the guitar next to it for a sense of scale. Apologies to any anal-retentive neat-freaks for the mess of cables and parts. I'll be the first to admit that my music room can get pretty messy.

    How do they sound? I've always loved those little guys, even with their poor, rough midrange.

      Very nice look, Paul! "DCR"s, eh? Good name.

      So, yeah- how do they sound? I've been wanting to hear the DC50 again, as it's been about 7 years since I heard it.

      You also have to love that HUGE flange on mid-domes of typical variety, dontcha? :rolleyes:

      I hope to hear them.
      Later,
      Wolf

      PS- a "classic revival" of the ZDT's too...

        Interesting design Paul, I like it! I've never heard the DC50 but I'd like to give it a go. Are the domes the sticky type? I'm a fan of the DC160 in a 3-way, I built a pair of towers 3 yrs ago w/ 4 DC160's a side and love it. Good solid bass. Any chance of seeing some measurements in the future?

          Paul,

          Does it jam hard enough for you to practice along with your drums?

            Hey Paul,

            I'm also interested in how these perform! This could be a great full range bedroom design, or be a quick simple into to the DIY world for friends.

            F3 of 34hz? Impressive. How's the impact, can you feel it nicely in the chest? How's it play at low levels and off axis?

            Thanks for another contribution!

            Russ

              I'm curious to see how these come out. The DC160 sounds boomy in the BR-1's, IMO. But Qts of .33 seems quite good and two in parallel might do the trick. Curt C has made great use of the 5.25" drivers. You might have found the ideal use for the awkward 6.5" sibling.

                I'm interested as well. Would love to see the XO.

                You've also convinced me to build a pair of Amiga cabs w/ removable front baffle and easily replaced crossovers.

                  Paul,

                  I think it looks like a great project. I think it would fit well for all of those friends of ours who aren't audiophiles and don't want to hear every last detail on the SACD, but just want a nice set of floor standing speakers.

                  You seem to be a speaker designing machine lately. Keep it up. :T

                    Reminds me of the Lyras, which I have running in my garage system to good effect. They look like they will make really nice music.

                    Another nice, resonably priced and sized design for the non-extreme crowd (thats some on this board and lots of folks off the board ;-)

                      Looks neat. I am reminded of these. Which I thought would probably be a ton of fun for someone who just wanted good sounding, loud ht speakers. Or something for rocking out.

                        Cool. Kind of like Matt's dual dc-160 system.

                          Last I heard on those, they still needed some XO tweaking.

                            Those look very nice.

                            Man, is that a monster flange on that mid!

                              The flange on that DC50 is disgusting. The project looks good though, I'm a fan of the TMWW.
